The cooking device can specifically be a device having a microwave heating function, such as a steam-microwave all-in-one machine, a bake-microwave all-in-one machine, or a steam-bake-microwave all-in-one machine.

[0042] Specifically, Figure 1 and Figure 2 As shown, the microwave generating device includes a solid source 1, a cable 2 and an antenna assembly 3, wherein the cable 2 connects the solid source 1 and the antenna assembly 3. The solid source 1 is used to emit microwaves, and the cable 2 connects the solid source 1 and the antenna assembly 3 to feed the microwaves into the cooking cavity 4 to heat the food in the cooking cavity 4.

Preferably, the solid source 1 is also arranged on the top of the cooking cavity 4 to shorten the length of the cable 2 and facilitate the connection between the solid source 1 and the antenna assembly 3.

When the microwave generating device is assembled in the cooking device, the connection surfaces of adjacent heat dissipation substrates 332 are parallel to the airflow direction in the heat dissipation channel 5, so that the airflow passes between the heat dissipation fins 331 on both sides of the connection surface, so as to reduce the obstruction of the airflow at the connection of the adjacent heat dissipation substrates 332.

[0052] Furthermore, if Figure 6 and Figure 7 As shown, adjacent heat dissipation substrates 332 are detachably connected by fasteners 333, and at least two heat dissipation substrates 332 clamp the antenna shaft 31 so that the heat dissipation substrates 332 are fixed on the antenna shaft 31. The fasteners 333 can be screws or bolts.

[0053] The heat dissipation substrate 332 includes a substrate body 3321 and connecting ears 3322. The connecting ears 3322 of adjacent heat dissipation substrates 332 can fit together.

Specifically, two first antennas 321 are provided, the two first antennas 321 are arranged vertically, and the second antenna 322 is arranged horizontally and connected to the lower end of the first antenna 321, and the two first antennas 321 and the second antenna 322 form an inverted F shape.

[0056] When the antenna assembly 3 is assembled to the cooking cavity 4, the heat sink 33 is first removed, and the antenna shaft 31 is passed through the through hole on the top side of the cooking cavity 4 from the inside of the cooking cavity 4, so that the flange 34 is against the inner side of the cooking cavity 4, the flange 34 is fixed to the cooking cavity 4, and then the heat sink 33 is assembled and fixed to the antenna shaft 31.
